Commit-msg: This hook is run before the commit is completed, but it runs after the commit message has been created. It can be applied to verify the format or content of the commit message. Post-commit: This hook is triggered after a commit. It can be used to perform actions such as sending notifications or updating documentation.

Pre-push: This hook is triggered before a push to a remote repository. It can be used to perform checks or actions to ensure that the push is allowed. Pre-receive: This hook is triggered on the remote repository before any references are updated. It can be used to enforce policies on incoming commits.
